for the 14" entry barrel you can do a search with the ATF
the 14" barrel is for LEO/GOV use or FFL's. Unless youre one of those. Take it off your mind. Actually Signal20 I am "one of those", but just as a law abiding citizen I can legally own short barreled shotguns, short barreled rifles, suppressors and automatic weapons, in the state that I live in, after doing the proper paperwork and paying certain fees. Check with the ATF again or maybe even talk to your friendly local Class III Dealer. They will be able to tell you all about it. I do thank you, however, for your concern for my well being.
